HOMER A. IIERR, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO THE AMERICAN CASH REGISTER COMPANY.

CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 451,232, dated April 28, 1891.

v Application filed August 3, 1889. Serial No. 319,660. (No model.)

To aZZ whom, it may concern.-

Be it known that I, HOMER A. IIERR, of the city and county of Philadelphia, and State of Pennsylvania, have in vented an Improvement in Cash-Registers, of which the following is a specification.

My invention has reference to'caslrregisters; and it consists of certain improvements, all. of which are fully set forth in the following to specification and shown in the accompanying drawings, which form part thereof.

My invention is for an automatic cash reg= ister and indicator adapted to record the amount of the purchases and disclose or in- T5 dicate to the purchasers the amount of individual purchases.

Among the novel features of my invention may be mentioned a series of vertically-movable registers, one or more for each key, the

indicators for the amount of the purchase operated by moving from in front of the figures a blank screen, and thereby exposing the figures corresponding to the key struck, the locking of all of the keys but the one struck the instant said key is moved to a slight extent,

and resetting devices controlled by an indicator-lock, which shall indicate the number of times said lock is opened. In addition to these features are a number of details of 3c minor importance, fully referred to hereinafter.

Referring to the drawings, Figure l is a front elevation of my improved cash-register with a portion of the frame and keys broken 3 5 away. Fig. 2 is a sectional elevation of same on line on w of Fig. 1. Fig. 3 is a sectional elevation of a portion of my machine, looking from the rear and with the covering at the back broken away. Fig. i is a side elevation of the registering mechanism in a different position from that shown in Fig. 2, and shows such mechanism removed from the frame of the machine and other operating devices. Fig. 5 is a rear elevation of the registering mechanism for registering the number of times the door has been open for resetting the machine. Fig. 6 is a sectional side elevation on line y of Fig. 1, showing the means for locking the levers when the draw is opened. Fig. 7 is a plan view showing the lock fol-holding the draw closed and the spring device for forcing the draw out upon being released from the lock. Fig. 8 is aportion of one of the dogs used in connection with the indicator mechanism. Fig. 9 is a frontelevation of one of the registering-slides, and Fig. 10 is a section on line .2 .2 of Fig. 3.

Before describing the invention in detail I would remark that for each operating-lever there is a corresponding duplication of mech- 6o anisin for registering and for indicating the amount of the purchases, with the exception that there is but a single drawer for all of the levers, and which is controlled by any and all of said levers or keys.

A is the main frame of the machine, and consists of a casting of any particular shape desired. To this frame are pivoted a series of levers B, having finger-plates 1), upon which is marked the amount to be indicated and registered by a movement of the lever. These levers are in effect keys, and are adapted to be struck by the fingers, one or more at a time. The finger-plate portions I) extend beyond the case A, so as to be given operative 5 position. The other ends of the levers project inwardly and produce directly or indirectly the various movements necessarily resulting from the construction embodied in my invention.

I will describe the parts employed in connection with one lever B, and thereby in effect describe the construction of all the levers and their mechanism. The inner end of the lever B rests against the underside of a table 0, projecting from a pivoted arm C. The upper surface of the table supports, through a roller or otherwise, a vertical rod D, having at its middle a hooked portion (1, and at its top a screen D, which, when the 0 rod D is down, slides or screens the tabletE, upon which is marked the amount of the purchases, corresponding to the finger-plate b of the lever B.

c is a glass, through which the tablet may 5 be observed, as indicated in Fig. 1.

F is a frame pivoted to the main frame A at F, and is provided at its upper end with a catch f, adapted to proj ect under the hooked portion (1 of the rod D, and thereby tempo arily sustain it in an elevated position, and so as to expose the tablet E. Pivoted to the arm of this frame F is a dog G, having an arm g, which in its downward movement strikes against and crosses frame f of the frame F and tends to move with it. The other end of the dog is made curved and expanded,as shown, for instance, in Figs. 2, 3, and 8, and this expanded portion of the dog is adapted to be struck by the upper or free end of the pivoted arm C. It will now be seen that by depressing the lever B at Z) the rod D is raised, and the arm 0 is oscillated thereby, the end striking the expanded portion of the dog G, and through it tilting the portion fof the frame F backward, to let the hooked portion (Z of the rod D pass above it. Immediately this takes place the end of the arm 0 slips beyond the dog G and allows the frame F to oscillate in the opposite direction, causing the catch portion f to catch under the hooked portion (Z, and thereby hold the screen D and rod D in an elevated position, exposing the tablet E to view. The weight of the series of dogs acts to bring the arm F normally to the position shown in Fig. 2, and also to cause it to move in looking the elevated rods D. It is evident, however, that a spring G might be used, if so desired, to return the frame F to the position shown. By liberating the lever B the arm O returns to the position shown in Fig. 2, and the dog is oscillated like a pawl, allowing the descent of the arm 0 without operating the frame F. It will thus be seen that the screen D, corresponding to the lever B, which is struck, is raised and locked in said raised position, while the lever B returns to its original position by the action of gravity.

To the inner end of each of the levers B is pivoted a hanging arm II, having at the bottom a head 71,, (shown in Figs. 2 and 3,) which arms project through slots h in the frame ll, which is pivoted to the main frame A. The parts H may be formed with levers B in any suitable manner so that they so move with said levers. The vertical movement of the arm H, caused by the lever B, oscillates the frame H so as to depress the locking-hook ll at the opposite end thereof. This hook H catches upon a catch-bar 2', secured to the rear of the drawer I, which drawer is arranged at the lower part of the machine. When the drawer is shoved in, the hook is depressed until it passes beyond the catch-bar i, and the weight of the outer end of frame H causes said hook to snap upward and lock the drawer. To prevent the drawer being forced upward at moment of locking, the piece I may be employed at its upper part and a guide I be used on the main frame. To the rear of the end of the frame 11' is a bell J, which is operated by a link connection j, moved by the said frame H, or, if desired, by any other equivalent movable portion of the machine.

To the rear of the arm H is a frame H pivoted to the main frame, and may be oscillated by a projection H from the frame H, working in a guide 7L3 on said frame 11 The object of this mechanism last described is that when the frame II is raised by the arm II and lever-B the frame H is oscillatedand its lower part is forced above the projections h on the arms H of the various levers B, except the one which is operating 011 the frame II, this one having risen sufficiently to enable its projection h to have passed above the end of frame II in its inward movement. It is immaterial to myinvention how the projections it, over which the frame ll passes, are connected with the levers B so long as they are moved by the movement given to said levers, and the frame acts to lock said projections against movement to lock the corresponding levers. This looks all the lovers but the one actuated intentionally, so as to prevent accidental registering when the drawer is closed.

It is not intended to register but by the ac-.

tion of one key at a time. \Vhen the. lock H" releases the drawer I), the two bell-cranks K, through their rollers 76, force the drawer outward, owing to their ends being drawn together by the action of the spring K. This is clearly shown in Fig. 7. The drawer in this figure is out, and if pushed inwardly would strike the rollers 7s and move the bellcranks K, as indicated by arrows, and expand the spring K, thereby storing energy which might be utilized upon the release of the drawer to positively force it open.

It will be seen from the construction above described that I have in a cash-register a series of operating-levers provided with projecting parts h, which are movable with the levers, and said devices are combined with a pivoted frame H adapted to be thrown into the path of the projecting parts of said operating-levers, so as to prevent the movement of all of said levers except the lever or levers intended to be struck,and a movable lockingframe operated byone of the levers,and common to all of'said levers for oscillating the pivoted frame to lock all of the levers than the lever or levers struck, to prevent such locked lovers from being moved or operating the registering parts or slides.

Below the levers B is a frame B, pivoted to the main frame of the machine at b, and is adapted to be turned up under the levers when the drawer I is pulled out, so as to prevent any of the levers being accidentally pushed down. To operate this frame B there is a tooth B on the side or end of the drawer I, which fits into a notch B on the frame. This is clearly shown in dotted lines in Fig. 2 and in detail in Fig. 0. Referring to the latter figure, when the drawer is pushed in the frame B assumes the position shown in dotted lines, releasing the levers B.

I will now refer to the registeringmechanism, which is clearly shown in Figs. 2 and t. There may be one or more registering-slides to each lever B, two being shown. For small machines only one would be used. The front slide M is formed with ratchet-teeth and is guided upon the upright guide-rods M m, so as to be capable of being moved vertically by a pawl 19, hinged to the lever B. The face of the slide M is formed with figures corresponding to the number of notches or teeth multiplied into the amount of the purchase. Thus.

if the slide is to register the number of livecent sales, then for the first tooth it will have a mark 5, for the second 10, for the third 15, and so on. This registering-slide when raised by the pawl P moves back of a plate WV, having the amount of the purchase corresponding to this slide marked thereon, as shown in Fig. 1, and the figures on the slide are exposed under the edge [0 and may be read through the doorway when the door Y is opened. If desired, the opening under the ed e w may be a slot. hen the pawl P raises the slide, the said slide is held in its raised position by the sustaining pawl 0 working in the same ratchet-teeth. In taking the amount of the sum total of the purchases it is necessary to add together the amounts shown on the registering-slides M exposed immediately below the edge 10. After the slide has been raised and it is wished to reset the machine to zero means are operated by hand which may remove the action of the pawls and allow the slide M to fall so as-to rest upon the frame Q, Fig. 2. This mechanism consists of a sliding frame R, guided upon the rods M m and to the rear of the slide M, having at the bottom the two teeth 0'' 0, which project under the pawls, and so as to throw them out when the frame R is raised, and at ornearits top a stop R in the path of the slide M. The frame R is hung upon the lever S, pivoted to the main frame, and this lever S is operated by a pivoted weight S to lift the frame R. The free end of the lever S rests against the projection or tooths of the weight S. When the slide M is raised sufficiently high that it strikes the stop R, the frame R is raised, depressing the free end of the lever S. This oscillates the weight S and causes it to fall over upon the leverS, as shown in Fig.4, causing the frame R to be raised, and by the teeth r 1' both pawls P and O to be thrown out of action with the ratchetteeth of the registeringslide. The instant this is done the slide M falls by gravity until itis arrested by the frame Q. If one set of registering-slides is used, then it will never happen that the weight S will be operated automatically, but will be oscillated, when desired, by the rock-bar V, formed, essentially, with two ribs or teeth, and being moved by hand so as to act upon the teeth or fingers s s of the weight S to throw it upon the lever S. When the slides M have thus been reset, the weight S is thrown back again into the position shown in Fig. 2, so as to allow the pawls P and O to come into play once more.

An additional registering-slide N may be used, if desired, and would be placed to the rear of the slide M and so that the figures can be seen through the spaces between the other slides and below the edge 20 of the rear frame XV, upon which are the numbers corresponding to thenumbers 011 the corresponding levers B. This inner registering-slide N is guided upon the rods N n, and is also furnished with ratchet-teeth, as in case of the slide M. Pivoted to the rear of the slide LT is an arm P which may be oscillated vertically, being raised by the upward movement of the projection m on the slide M, striking part at of the arm, and falling by gravity when the slide M descends. Pivoted to this arm P is the actuating-pawl P for actuating the slide M with a step-by-step movement. This mechanism operates to move the slide one tooth for each full movement of the slide M. O is a pawl used to support the slide N when raised by the pawl P. This pawl O has an upward projection 0, which may be actuated by the pivoted rock-bar V when it is desired to reset the machine. \Vhen the pawl O is moved back to liberate the slide N in resetting the machine, it moves back with it the rod 0, and this, acting on the pawl P causes it to be moved out of contact with the slide N, also allowing said slide to fall by gravity.

1 would call attention at this point that after the slides are in the position shown in Fig. A the slide M falls, and when about its lowest position the projection or lug M thereof strikes the frame R and pulls it down, oscillating the lever S, so as to throw the weight S back to the position shown in Fig. 2 and allow the pawls P O to once more come into action. The mechanism is therefore automatic. Every time the drawer is opened it is evident that the bell J rings, and thereby sounds an alarm.

The frames V V for resetting the machine have their ends 1 v projecting through the side of the main frame A and adapted to be operated with a key. Arranged over these ends is a cover T, pivoted to the main frame at t, and provided with a lock t to lock it in its closed position. In addition to this lock there is a spring-bolt T, which is provided with a tooth 25, adapted to act upon the ratchet-wheel V. This ratchet-wheel is prevented from rotating backward by a pawl V and is furnished with a pin it, which, acting on the teeth of the notched wheel U, induces it to make a given portion of a revolution for every complete revolution of the wheel U. The latter wheel U is prevented against accidental movement by the double pawl 11, or, if desired, by a spring. (Shown in dotted lines.) The wheels U and U are countingor indicating wheels and indicate the number of reciprocations of the bolt T, and hence the number of times the cover is removedfor resetting the machine. hen the cover is pushed into lockin g position, the bolt T strikes the portion A, Fig. 3, of the frame A and is shifted. This mechanism prevents the attendant resetting the machine after having received and registered a number of purchases.

The general shape of the machine may be varied to suit the manufacturer, and may be all of metal or wood and metal combined. The front portion of the frame is furnished with a door Y, which opens outwardly and exposes to view the records, as shown on the slides M and N immediately below the plates \V. This door is kept locked, except when adding up the amounts of the records of the several slides M and N.

I do not confine myself to the mere details of construction, as it is quite evident that they may be modified in various ways without departing from my invention.

In this application I do not claim theregistering devices and locking-cover as applied to the resetting mechanism, as that forms the subject-matter of my application, Serial No. 325,415, filed September 28, 1889.
